Reply to Need help syncing two MacBook Pros with S4s to one MIDI clock

I'm trying to get two laptops running Traktor with S4s to sync using the MIDI in/out ports on the S4s.

I tried this tutorial from Traktor Bible:
http://www.traktorbible.com/en/kontr...ng_two_s4.aspx

I skipped step 3 because I'm going into a mixer, but did everything else. My only problem comes with setting up new devices on each machine. The tutorial says to use select the Traktor S4 MIDI port for output/input respectively on each machine. When I add a new device, I can only select None, Traktor Virtual Input/Output or All Ports.

I also tried this T Squared tutorial from Youtube:

The video is using Traktor though, not Traktor 2. None the less, I tried it and it didn't work either. But the video is basically the same as the Traktor Bible, save for the added steps of creating devices for the MIDI clock.

Either or, none of this has worked for me.

Can someone offer some advice. If you need more details, let me know.
